OnTime ⏱️

A powerful and flexible timer mod for Minecraft. Create custom timers with on-screen display, dynamic time expressions, event triggers, and a built-in web admin panel — ideal for minigames, events, modpacks and automated server tasks.

✨ Features

🕐 Timer System

Create and manage multiple named timers
Countdown and count-up modes
Start, pause, resume, stop, reset and remove timers at any time
Add or override time on active timers
Timers persist across server restarts and auto-resume where they left off
Repeat mode — loop a timer a set number of times or infinitely, with optional cooldown between repeats
Timer sequences — chain timers so the next starts automatically when the current finishes, with optional cooldown between steps
Per-timer files — every timer lives in its own config/ontime/timers/<name>.json, ideal for backups and version control
Export / Import / Clone — share timers between worlds or instances with /timer export, /timer import, /timer clone

🧮 Dynamic Time Expressions

Define a timer's duration with a math expression that's evaluated when the command runs
Supports + - * / %, parentheses, and live variables: players_online, score(<objective>, <holder>), ftb_quest_completed(<id>), ftb_reward_claimed(<id>)
Available on /timer expr create, /timer expr set, /timer expr add

🎯 Conditions & Triggers

Score conditions — finish (or start) a timer when a scoreboard objective reaches a target
Condition expressions — full boolean DSL with &&, ||, !, >, <, >=, <=, ==, !=, plus values like time_remaining, time_elapsed, players_online, score(...)
Vanilla event triggers — fire timers on player_death, dimension_change (any or specific dimension), advancement (specific ID)
FTB Quests triggers — fire on quest completion or reward claim by hex ID
Each condition/trigger can be configured to either start or finish the affected timer

🖥️ Server-Controlled Display

Real-time on-screen overlay synced to all connected players
Smooth, jitter-tolerant client rendering — the counter updates like a real wall clock with no visual desync
10 position presets: Boss Bar, Action Bar, Top/Center/Bottom variants, and Custom
Per-player visibility control — admins can show or hide the timer for specific players
Adjustable scale (0.1× to 5.0×)
Dynamic color gradient based on remaining time (configurable thresholds and colors)
All display settings are managed server-side and pushed to clients automatically
Active timer synced to scoreboard — ontime_active objective updated every second, usable with /execute if score
Jade compatibility — when the timer overlaps Jade's overlay, Jade is gently displaced; restored automatically

🔊 Sound

Configurable tick sound, volume and pitch via /timer sound
Per-player sound toggle managed by admins via /timer silent

⚡ Command Execution

Attach any server command to a timer, executed automatically on completion
Placeholder system: use {name}, {time}, {seconds}, {ticks}, {target}, {mode} in commands

🌍 Web Admin Panel

Built-in HTTP+SSE dashboard served by the mod itself — no extra server needed
View all timers in real time, start/pause/stop/reset, edit names/durations/commands/conditions, browse the history log, change display config
Auto-closes after 5 minutes of inactivity (with a 1-minute warning to ops); clean shutdown on server stop
Start/stop on demand: /timer webpanel start [port], /timer webpanel stop, /timer webpanel info
Default port: 25580

📋 History Log

Every timer completion is recorded in config/ontime/history.json with name, duration, mode, command and timestamp
Browsable from the web panel

⚙️ Configuration

In-game config screen via Cloth Config (and ModMenu on Fabric)
JSON config files in config/ontime/
Optional WebSocket server for external integrations (panels, Discord bots) — enable in config.json. Default port: 25581

🔌 API & Integrations

OnTime API — create, query, control timers and register event callbacks (onStart, onFinish, onPause, onResume, onTick)
External finish conditions — register a custom Supplier<Boolean> that can stop a timer from another mod
Custom renderer API — replace the timer HUD renderer entirely from a client-side mod
LuckPerms support — per-node permission control for every subcommand, with OP-level fallback
Entrypoint system — Fabric entrypoints and NeoForge/Forge IMC
Placeholder API integration (Fabric)
FTB Quests integration (compileOnly, auto-detected at runtime)
Jade integration (auto-detected at runtime)
